Tutorials

Lessons 1 and 2 teach basic RF concepts, and are a mix of movies, pictures, and text. I'm aiming to be helpful for the High School, College, and Amateur level, and any professional who wants to refresh their understanding.

Lessons 3 through 8 show how to use Mason for computer simulations. If you are a professional or knowledgeable amateur, you might also want to check out my Advanced Topics section.

Lessons 9 through 14 show actual applications with Mason as a simulation tool. These pages try to show more than just how to use Mason, but also how to design some simple circuits, including the folded dipole antenna with balun circuits shown on the front page. Users might also be interested in the Advanced Topic section.

If you can't find the answer, I have a "circuitmason.com" account, the address is at "Gregory dot Kiesel". If you can't figure that out, you are probably a bot.

Advanced Design Topics

When summing the signals of an antenna
array, it can be useful to use some flavor of a cosine taper. Rather
than using attenuators, some clever arrangements of Wilkinson combiners
can be used to produce a "lossless taper". This can be helpful in
improving the overall noise figure of the system.

Wilkinson combiners work, in part, as a matching network. As such,
broader bandwidths can be achieved by adding more elements. Some design
techniques for efficiently creating a broadband combiner are presented.
